FlexiReg: Flexible Urban Region Representation Learning
Fengze Sun, Yanchuan Chang, Egemen Tanin +2
The increasing availability of urban data offers new opportunities for learning region representations, which can be used as input to machine learning models for downstream tasks s…
TSMini: A Simple Yet Highly Effective Trajectory Similarity Learning Model
Yanchuan Chang, Dingyang Lyu, Xu Cai +2
Trajectory similarity is fundamental to many spatio-temporal data mining applications. Recent studies propose deep learning models to approximate conventional trajectory similarity…
DualCast: A Model to Disentangle Aperiodic Events from Traffic Series
Xinyu Su, Feng Liu, Yanchuan Chang +3
Traffic forecasting is crucial for transportation systems optimisation. Current models minimise the mean forecasting errors, often favouring periodic events prevalent in the traini…
Spatial-temporal Forecasting for Regions without Observations
Xinyu Su, Jianzhong Qi, Egemen Tanin +2
Spatial-temporal forecasting plays an important role in many real-world applications, such as traffic forecasting, air pollutant forecasting, crowd-flow forecasting, and so on. Sta…
Urban Region Representation Learning with Attentive Fusion
Fengze Sun, Jianzhong Qi, Yanchuan Chang +3
An increasing number of related urban data sources have brought forth novel opportunities for learning urban region representations, i.e., embeddings. The embeddings describe laten…
Trajectory Similarity Measurement: An Efficiency Perspective
Yanchuan Chang, Egemen Tanin, Gao Cong +2
Trajectories that capture object movement have numerous applications, in which similarity computation between trajectories often plays a key role. Traditionally, the similarity bet…
MaaSDB: Spatial Databases in the Era of Large Language Models (Vision Paper)
Jianzhong Qi, Zuqing Li, Egemen Tanin
Large language models (LLMs) are advancing rapidly. Such models have demonstrated strong capabilities in learning from large-scale (unstructured) text data and answering user queri…
